WILLIAM H. HALL, OF CIGERO, ILLINOIS, ASSIGNOR TO KOHLER DIE & SPECIALTY COMPANY, OF DE KALB, ILLINOIS, A CURPORATION OF ILLINOIS.

CHURN.

Application filed October 25, 1917. Serial No. 198,420.

I '0 all whom it may concern:

Be it known that I, VJILLIAM H. HALL, a citizen of the United States, residing at Cicero, in the county of Cook and State of Illinois, have invented certain new and useful Improvements inChurns, of which the following is a specification.

This invention relates to improvements in churns and similar apparatus.

The main andprimary object of the'pres ent invention is the prov1sion of novel and eilicient operating mechanism for the dasher and supporting means therefor, whereby to insurelight running and long service, and through the medium of which unsanitary conditions, so far as the operating mechanism is concerned, may be eliminated.

The invention further aims to provide suchan assembly of the operating mechanism and its support with respect to the removable top of the churn and to impart to the support the necessary strength to insure accurate positioning and manipulation of the dasher-operating mechanism, and also to economize inthe amount of material employed in the construction of the apparatus. Furthermore, the invention contemplates a novel form ofhandle member associated with the support of thedasher-operating mechanism by means of which the removable top of thechurn may be readily applied to and removed from the body thereof.

With these objects in View, and others which will appear as the nature of the improvementis better understood, the invention consists substantially in the novel construction, combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the appended claims. In the drawings- I Figure 1 is a side elevation, partially in section, of a churn constructed in accord ance with the present invention;

Figure 2 is a vertical transverse sectional view thereof taken on a line at right angles to the line of section of Figure 1; and

Figure 3 is a top plan view.

Referring now in detail to the accompanying drawings, the numeral 10 designates the body of the churn. This is preferably formed of heavy flint glass so as to be trans parent, but also to provide the requisite strength, although it is obvious that any other material may be employed. The top of the body 10 has a mouth 11 of wide dimension to facilitate access to the interior construction, said dasher being supported by a vertical shaft 16 the upper end of which is positioned within a depending guide sleeve 17 suitably positioned in an aperture in the top 14. The upper end of the shaft 16 is projected suificiently above the upper of the guide sleeve 17 to permit the application thereto of a pinion 18, and said pinion is connected to said shaft 16 by any suitable means, such as by upsetting the end of the shaft 16, and thus holding the pinion 18 in fixed relation thereto so as to rotate therewith. I

lhleshing with the pinion 18 is a vertically disposed gear wheel 19, the teeth 20 of which are formed at one of its edges so as to engage the teeth of the pinionv 18, and said to the outer end of which is connected a crank 23 by means ofwhich said shaft 22 maybe rotated. The inner end of the shaft 22 projects exteriorly of the supporting bracket about to be described so as to position the gear .wheel 19 at the exterior of said bracket. The shaft 22 is journaled in a supporting bracket 2st arrangedat one side of the center of the top 1-1 which bracket'includes a pair of upwardly extending parallel arms 25 and 2b united at their upper ends by a connecting web 27, said arms 25 p and 26 being provided with alined openings wherein the shaft 22 is seated. The arms 25 and 26 are respectively provided with inwardly directed supporting feet 28 and 29, said supporting feet being suitably connected to the top 1 1-, preferably by spot welding. The supporting feet 28 and 29 extend at approximately right angles to the arms 25 and 26 and towards the axis of the body 10, the foot 29 being positioned adjacent the edge of the top 1 1-, while the foot 28 is disposed at substantially its central portion and perforated for the passage of the dasher shaft 16. The foot 28 acts as a support for the pinion 18, which latter constitutesthe head of the dasher mechanism.

In order that the cover 14 may be readily applied to and removed from the body 10 of the churn a handle yoke 30 is arranged on said cover portion at a point opposite to the supporting bracket 24 and in alinement with the latter. This handle yoke comprises a vertical arm 31 and two parallel horizontal arms 32 and 33 arranged at the ends of said vertical arm 31, the lower horizontal arm 32 serving to connect the yoke 30 to the top 14, while the upper arm is free. That this may be effected the arm 32 is preferably spot welded to said cover it, but any other means for connecting it may be employed. As disclosed in the drawings, the handle yoke 30 is indicated as a separate construction from the supporting bracket 24., the inner end of the lower'arm 32 being arranged in overlapped relation with respect to the supporting foot 28, but if desired it will be understood that the horizontal arm 32 may be made an integral part of the supporting foot 28, thereby forming the supporting bracket 24; and the yoke handle 30 as a single unitary structure.

While the herein described invention is primarily designed for use in the production of milk-charged butter, which is a compound of commercial butter and a proper percentage of sweet milk, it is capable of use as a churn to make regular butter direct from cream; as a cream and egg beater; as an ice-cream freezer; as a cake and batter mixer; as a butter renovator, and for other similar purposes. When required for such use the ingredients are placed within the body 10, the cover 14 being suitably connected to the body by threading the flange 3 upon the threaded neck of the body 10, thereby introducing the dasher 15 to the ingredients, and the dasher 15 is operated in the usual manner of a churn. Inasmuch as the dasher and its shaft, together with the operating mechanism therefor and the support for such mechanism are carried by the cover 14-, all of the operative parts are re moved from the body 10 when the cover 14: is removed therefrom. The supporting bracket 24 and its attaching feet 28 and 29 provide a rigid mounting for the shaft24= and the gear wheel 19 carried thereby, and the yoke handle 30 being arranged in opposite relation to said supporting bracket 24 there is provided a convenient means for grasping and carrying the churn or removing the cover 14: from the body 10 when such is desired.

The construction described also provides a churn which is highly sanitary, light running in operation, and adapted to long service by reason of the minimum number and the strength of the parts incorporated in the churn structure.

I claim:

. 1. In a churn, the combination with the body thereof, and a cover therefor, of dasher mechanism carried by said cover operating mechanism for said dasher mechanism, and a handle yoke associated with said operating mechanism, said handle yoke including a vertically extending arm and a pair of parallel horizontal arms extending from the ends thereof, the lower of said arms being suitably connected to said churn cover for holding the handle yoke in association therewith, and the upper arm being free.

2. In a churn, the combination with a body thereof, and a cover therefor, of dasher mechanism carried by said cover, a supporting bracket arranged at the exterior of said cover and comprising a strip bent to form a pair of parallel vertical arms, a connecting web extending between said arms and uniting their upper ends, and attaching feet arranged at the lower ends of said arms and extending inwardly therefrom at right angles thereto and towards the axis of the body, said attaching feet being separated from each other and suitably connected to the cover tohold the vertical arms of the supporting bracket on the cover, said verticalarms being provided with alined perforations, a horizontaloperating shaft journaled in said perforations and having its inner end screw-threaded and projecting exteriorly of the supporting bracket, a drive gear threaded upon the projecting inner end of said operating shaft and meshing with the dasher mechanism, the upper end of the dasher mechanism passing through the attaching foot of the inner of said vertical arms, said attaching foot acting as a support for the head of the dasher mechanism, and means for actuating said shaft.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
